Abstract: The goal of this paper was to incorporate Phase-Change Materials (PCMs) into asphalt in order to reduce the amount of heat that the pavement absorbs. Asphalt pavement is vastly preferred to cement for roads, however the downside is that it can reach extremely high temperatures during daylight hours, which can increase the heat island effect and cause deformation in the road surface. The thermal and mechanical properties of asphalt with two different PCMs incorporated were investigated. The Hot Disk TPS was used for all thermal conductivity measurements. The authors discovered that the two PCMs used had substantially different effects on the asphalt properties.
